Hose Clamps that are designed to accommodate and variable hose diameter, Including Rotor's Spring Band Hose Clamps, Double Wire Spring Hose Clips & Mikalor's Constant Tension ASFA Worm Drive Product. Constant tension hose clamps are specialized fastening devices designed to maintain a consistent clamping force on hoses, accommodating thermal expansion and contraction. These clamps are essential in automotive applications, particularly in environments where temperature fluctuations can lead to leaks or hose blow-off. Unlike traditional screw-style clamps, constant tension clamps automatically adjust their grip as conditions change, ensuring a reliable seal under varying pressures. This feature makes them ideal for high-performance settings, such as turbocharged engines, where maintaining boost pressure is critical for optimal performance. Their robust design and ability to resist corrosion further enhance their reliability in demanding conditions.
